Differential cargo mobilisation within Weibel-Palade bodies after transient fusion with the plasma membrane. [PDF]
, 2014 Inflammatory chemokines can be selectively released from Weibel-Palade bodies (WPBs) during kiss-and-run exocytosis. Such selectivity may arise from molecular size filtering by the fusion pore, however differential intra-WPB cargo re-mobilisation ...

An Approach to Monitor Exocytosis in
, 2020 Exocytosis, the fusion of vesicles with the plasma membrane, can be measured with the patch-clamp technique as increases in membrane capacitance. Here we provide detailed information on how to monitor white adipocyte exocytosis using this method.

Focal exocytosis by eosinophils‐‐compound exocytosis and cumulative fusion. [PDF]
The EMBO Journal, 1993 We have investigated the granule fusion events during exocytosis in horse eosinophils by time-resolved patch-clamp capacitance measurements. Stimulation with intracellular GTP gamma S leads to a stepwise capacitance increase by 4.0 +/- 0.9 pF. At GTP gamma S concentrations < 20 microM the step size distribution is in agreement with the granule size ...

Frontiers in Physiology, 2012 We review the evidence of exocytosis from extrasynaptic sites in the soma, dendrites and axonal varicosities of central and peripheral neurons of vertebrates and invertebrates, and how it may contribute to signaling in the nervous system.

SNAP23 Regulates Endothelial Exocytosis of von Willebrand Factor. [PDF]
PLoS ONE, 2015 Endothelial exocytosis regulates vascular thrombosis and inflammation. The trafficking and release of endothelial vesicles is mediated by SNARE (Soluble NSF Attachment protein REceptors) molecules, but the exact identity of endothelial SNAREs has been ...

An inhibitory effect of extracellular Ca2+ on Ca2+-dependent exocytosis. [PDF]
PLoS ONE, 2011 AIM: Neurotransmitter release is elicited by an elevation of intracellular Ca(2+) concentration ([Ca(2+)](i)). The action potential triggers Ca(2+) influx through Ca(2+) channels which causes local changes of [Ca(2+)](i) for vesicle release. However, any

The light chain of tetanus toxin inhibits calcium-dependent vasopressin release from permeabilized nerve endings [PDF]
, 1992 The effects of tetanus toxin and its light and heavy chain subunits on vasopressin release were investigated in digitonin-permeabilized neurosecretory nerve terminals isolated from the neural lobe of the rat pituitary gland.

PLoS ONE, 2020 α-Klotho is a type 1 transmembrane protein that exhibits aging suppression function. The large amino-terminal extracellular domain of α-klotho is shed as soluble klotho (sKlotho) and functions as a circulating cardioprotective hormone.
